Whirr Sleep

Whirr Sleep generates continuous, customizable noise to help you fall asleep, stay focused, or block out distractions. Choose from five tuned presets or adjust Intensity, Deepness, and Texture to craft your perfect sound. Set a sleep timer and lock your phone. Whirr keeps playing through the silent switch, on the lock screen, and in the background. Try it free for three days, then unlock forever with a single purchase.
